6. Which point on the number line shown best represents 0.39?

Point W

Point X

Point Y

Point Z

Point Z represents 0.39 on the number line because it is the closest point to zero. The number line starts at zero and increases in value as you move to the right. Since 0.39 is a positive number, it is to the right of zero, and Point Z is the closest point to zero among the given options.

Explanation

Point Z represents 0.39 on the number line because it is the closest point to zero. The number line starts at zero and increases in value as you move to the right. Since 0.39 is a positive number, it is to the right of zero, and Point Z is the closest point to zero among the given options.
